The invention concerns an arrangement for taking samples from a suspension flowing in a pipe section 1. Across the direction of flow of the suspension is arranged a pipe 3, which is provided with a continuous hole 4 in the area for the intended sampling, whose axis lies in the flow direction. A piston 8 can be moved in the pipe 3 and is provided with an opening 9 accommodating a filter screen 14. The piston 8 has such length on one side of the opening 9 that upon movement of the opening and thus the filter screen 14 from a position coinciding with the hole 4 in the pipe 3, for taking a sample, to a position outside the pipe section 1, where the sample can be removed from the opening 9 in the piston 8, the piston 8 will cover the hole 4 in the pipe 3. <IMAGE> |
